About the Snake River

Fly fishing on the Snake River is an experience you won’t forget. The Snake River is just minutes away from the town of Jackson Hole and Grand Teton National Park, making it an easy journey to some of the best fly fishing in Wyoming. Often called the hatchery stretch, this river boasts a variety of bugs, birds, plant life, wildlife, and more.

 

Created by the confluence of three small creeks in Yellowstone National Park, the Snake River makes an impressive 1,078-mile journey from the corner of Western Wyoming, all the way to the Columbia River in the Pacific Northwest. Its flow is influenced by snowmelt from the surrounding mountains, resulting in higher water levels in spring and early summer. The river’s tributaries and springs ensure a steady flow and clear water conditions, ideal for your Jackson Hole fly fishing trip.

Best Times & Seasons

Snowmelt from the surrounding mountains drives the Snake River’s seasonal flows. High water in spring (April–early June) can make fishing challenging, while summer and early fall offer the clearest water and most productive hatches. As the USGS CFS graph below shows, flows typically peak in late spring and drop steadily through September. For the best dry‑fly action, target stoneflies and mayflies in June and July; terrestrials such as grasshoppers and ants become important in August and early September. Fall (September–October) is an excellent time for streamers and nymphs, when big cutthroat trout prowl deeper pools.

Fish Species & Fly Hatches

Anglers flock to the Snake River for its exceptional trout fishing, with the most sought-after species being:

  • Snake River Fine-Spotted Cutthroat Trout: Native to the river and renowned for its dense pattern of small spots.
  • Mountain Whitefish: Abundant and often found alongside trout.

 

Key Hatches include:

  • Stoneflies: Especially the Skwala, which is a sought after hatch.
  • Mayflies: Such as the Hecuba and Snake Drake.
  • Caddis flies: Various species, with peak hatches in summer.
  • Terrestrials: Grasshoppers and ants, prevalent in late summer and early fall.

Fishing Tips & Techniques

  • Best Spots: The Snake is vast and varied, including several “fishy” side channels and tall canyon walls. Target areas with deep pools and undercut banks where trout hide. 
  • Fly Selection: Use flies that match the current hatch by looking for signs of insect activity on the water and visit local fly shops for their suggestions. 
  • Techniques: Both nymphing and dry fly fishing work well. Streamers are useful in deeper waters for larger trout.
  • Equipment: A 4-6 weight rod is suitable for most conditions on the Snake River. Adjust your strategies based on water flow and conditions.

For walk‑and‑wade anglers, side channels near Moose, Wilson and South Park offer productive water with easy road access. Always respect private property and check the Snake River Management Plan for designated access areas.

Regulations & Licensing

The Snake River is managed according to Wyoming state fishing laws and regulations. All anglers aged 14 and older must have a valid Wyoming fishing license, which can be purchased online or at retail outlets in the Jackson area. Within Grand Teton National Park, all cutthroat trout caught in the Snake River must be released from November 1 through March 31, and certain sections of the river are closed during winter months. From the gauging station below Jackson Lake Dam to the Wyoming Highway 22 (Wilson) Bridge, only artificial flies and lures may be used. Familiarize yourself with creel limits and seasonal closures before fishing, and consider pinch‑barbing your hooks and practicing catch‑and‑release to protect native trout.

Historical Information

Not only is the Snake River rich with fish, but it also holds a longstanding history. Native American tribes, including the Shoshone, relied on the river for sustenance and transportation. During the 19th century, fur traders, trappers, and pioneers used the river as a crucial navigation route. The Snake River was also a key part of the Oregon Trail, facilitating the westward expansion of settlers. The Snake has played a significant role in the history of fly fishing and the evolution of the sport.

Below, you’ll find the latest USGS graph displaying the current Cubic Feet per Second (CFS) discharge of the Snake River below Flat Creek near Jackson Hole, Wyoming where our Snake River fly fishing trips take place. This crucial metric fluctuates seasonally, with the highest flows typically occurring in spring due to snowmelt in the surrounding mountains. As winter approaches, the CFS usually drops, reflecting the river’s calmer, lower volume state. Understanding these CFS trends is very helpful when determining current fishing conditions, as they directly impact river conditions and fish behavior. Use this graph to stay informed about the Snake River’s fly fishing conditions for a safe and successful fishing experience!
